Note 20 — Chapter III · CATEGORIÆ.
Reading edition
Aristot. Categ. p. 3, a. 20. It appears that Andronikus did not draw the line between these two classes of predicates in same manner as Aristotle: he included many non-essential predicates in τὰ καθ’ ὑποκειμένου. See Simplikius, ad Categorias, Basil. 1551, fol. 13, 21, B. Nor was either Alexander or Porphyry careful to observe the distinction between the two classes. See Schol. ad Metaphys. p. 701, b. 23, Br.; Schol. ad De Interpret. p. 106, a. 29, Br. And when Aristotle says, Analyt. Prior. i. p. 24, b. 26, τὸ δὲ ἐν ὅλῳ εἰναι ἕτερον ἑτέρῳ, καὶ τὸ κατὰ παντὸς κατηγορεῖσθαι θατέρου θάτερον, ταὐτόν ἐστιν, he seems himself to forget the distinction entirely.
